ELEVA'IOR.l

To all whom it may concern: Y

Be it known that I. Sioirt'xo L. GoLnMAN. a citizen of the UnitedStates. residing at Chicagorin the countv of Cook aud State of Illinois.have invented a new and useful Im- ..1n:1vement in Efevators` of whichthe following is a specification.

illy invention lrelates to certain new and useful improvements melevators, and is l-fullv described and explained in the specificationand shown in the accompanying drawings. in which: l

Referring to the drawings`A is the lower end of a gravity conveyercomprising a framework and rollers upon which boxesor similar articlesmay move by accordance with the practice which is now A1 isadischarge-slide which is pivoted Vbetween its ends to the lower end ofthe gravity-conveyer, as illustrated in Fi 1. 2, 3 and 4, from which itwill he'seen't atl the discharge-slide is so arrangedthat when in itslower position, it. will h ave its upper end projected into the path ofthe articles moving on the convegver so as to stop their movement asshown in Fig. 1, and when raised to the position shown in dotted linesin Fig. l, will have its upperend so depressed as to permit theirpassage thereover. Downward movement of the discharge-sliderbeyond theposition shown in .solid lines in Fi 1 is prevented bv the engagement ofpro] ecting ears a.; with fingers a? on the lower end ofthe 4convever.

and at its upper and forward enda shaft ZH,

upon which shafts are mounted sprocketwheels over which run chains C.The cha ins are guided i'n channel-irons b2 which ruu along both theupper and lowerhorizontal and curved portions of the conveverand'continue throughout the lower slanting portion thereof. andangle-irons b3 which' extend along the upper portion of t-he slantingpart of the conveyer frame. the said angles and vso channels beingdisposed attheir flange ends,

tlieangles having their flanges beneath the chains to prevent saggingthereof. Atintervals along the 4cham C are .located brack- .ct's 'whichare opposite to each other upon the two chains and .which said bracketsarc connected b v cross-bars C1, the bracke'tsand cross-bars formingtogether flightsfor the propulsion of articles. Two links in advance ofeach of the brackets area series of cross? barsCz. I ving inV the planeof the chain and oil the next preceding links are a. series of flatcross-straps C3, C, thejlinks C carrying the en 'ds of' which are curvedownfwad"asI the curve for a shortdistance and the'cenp t-ral straps'D1for a somewhattance upward. p l

E is an upper conveyor, in form like the conveyer A, so positioned as toreceive argreater dis# ticles delivered by the elevator in the manner tobe explained. l

- The manner of operation of the'entire structure is as follows: Theparts normally occupy positions as shown in Fig.f 2,f in which the boxesor cases on the conveyer A are arrested b v the upwardly rojecting endof the discharge-slide A1. [j sone of the flights. moves alongras to theposition show-n in dotted lines in Fig. 1. it 4 raises thedis;charge-slide A1 to the position' shown in dotted lines 'in that figure",and the lastl box or case in 4 the series moves onto thedischarge-sllde, sliding down the same after the, flight advancesand'permits the disV 4shock or tion. Tliilsai'tier the passage of aflight past the discharge-slide one box or case will be 'found inanincline'd position on the discharge-slide vwith its lower forwardcorner the itto fall flat on the fingers C5 upon which it will moveforward until said fingers are inclined vby passing upthe angular partof the elevator upon which the box will slip backward. taking a positionfirst like that shown by the rear-most box illustrated in dotted linesin F 2 and finally, when the curve is completely past by the flighttaking the position shown in dotted lines for the second box, afterwhich the box or case occupiesl a fixed and definite relation withreference to the flight and fingers and may be carried for anydistance'upward withrelative movement between said ately below the levelof the chains is filled .up' m'ore or 'less completely by, the strapswhich extend upward vto apo'mt at which the box or case takes its finalvadjustment after which they are no longer necessary.

When a box or case reaches .the upper end of theelevator andthe fingersCs upon which it principally rests begin to turn-with reference to the'flight, the box moves through the various positions illustrated in Fig.2*, being finally' discharged without jar onto the upper. conveyerA asillustrated.

It is to be seen that. the 4elevator thus described is simple and lcheapin its construe# tion, that its operation is certain and that the' boxor case is subjected to no considerable jars'by which it or its contentsmight be injured. The construction as a Whole is thoroughly etlicient inoperation and is free from the objections ap lying'to many types ofelevators particular y in that there is no opportunity for the box to bepinched between the ilights and any. projection either in the chain or.its connection or on the elel va'tor itself, as is the case with chainelevators and certain other types of construction.

' I realize -that considerable variation is possible in the .details ofconstruction of my improved' device, without i departing from the spiritof my invention, and I do not intend therefore'to limit myself to t-hespecific form herein shownand described.

What I claim as new, and desire to secure 1. The combination with aconveyeriand a discharge-'slide at" the end thereof pivoted between itsends whereby-its upper end can project into the path Jof articles on theconsuch articles may elevator' the discharge-slide in their passagetoper slide being adaptedl to support the articles while passing from theconveyer to the ele# vator. l

2. In combination,` a conveyer, a discharge-slide pivoted between itsends adjacent to the end of a conveyor whereby its upper end can projectinto the path of articles-'upon said com-'eyer, an elevator-chainprovided with flights disposed beneath the discharge-Slide, the flightsbeing arranged to contact with the discharge-slide to elevate the same,depressing the upper end thereof to release packages moving upon theconveyer said dischaigey slide being adapted to 'support the articleswhile passing from the conyeyer to the elevator.

3. The combination with a conveyer and an elevator adjacentthereto, of adischargeslide swingingly connected to said convey-'er and adapted whenin lowered position to forma stop to retain articles thereon and whenraised to form an incline down which travel to the surface of, theelevator. g

4. In combination, an inclined elevator for conducting packages upwardand a conveyer inclined downwardly from a point ad- -jacent the upperend of the elevator, said elevator comi-rising l package-supporting4sel'iarated flexible members free at their for- "ward ends. forming aslatted platform adapted to extend outwardly in the plane offthedownwardly inclined conveyer at the curve 0f the elevator'at its upperend, wherelby packages restinff on said flexible members are dischargedfi'om the elevator to the conveyer without substantial tilt or j ai'.

- 5. In combination, an inclined elevator for cond-noting packagesupward and a conveyor inclined downwardly from a point adjacent theupper end of the elevator, said comprising package supporting separatedflexible members free at their for-V ward ends forming a slattedplatform adapted to extend outwardlyy in the plane of the downwardlyinclined conveyer at the curve of the elevator at its upper end and topartially bridge the space between the elevator and conve-yer, wherebypackages restin on said flexible members are discharged rom the elevatorto the conveyer without substantial tilt rjar.

6. In combination, elevator chains guided to travel lirs; in asubstantially horizontal and then in a diagonally upward direction forthe elevation of packages, flights carried by the chains, andintermediate flat package-carrying members mounted at their rear ends-onone link only of each chain and free at their forward ends, whereby saidpackage-carryinor members afford elastic carriers for the pac 4ages andare adapted to conformto the curve of the elevator chains at yward at anangle, flights lcarried by the respective ends of the traverse of saidchains, as set forth.

7. In combination, a cha-in guided to run first in a horizontal and thenin anupwardi'y inclined plane, flights carried by the chain, a pair ofcross-bars extending between the chains, a series oflongitudinally-extendin' Hat-fingers carried by the rear-cross-bar anarranged to be supported by the forward cross-bar.
